. To all whom it 'may concern:

Be it known that I, ROBERT A. OGLE, av

' /citizen oi" the United States, residing at Chicagohin the county oi'Cook and .State of` Iliinois, have invented a new and usefulAimprovement in Loaders, ofj which the following is a speciilcation.

My invention relates more particularly to apparatus for elevating' coaliroin a hopper to a receptacle. to be loaded, as for instance a bin fromwhich a supply of coal is furnished to a locomotive tender.

In cooling stations the hopper or chute for receiving the coal ispreferably positioned below the level of the ground, that the tracks, onwhich the train from which the hopper is supplied, need not be elevated.The location of the hopper below the ground necessipermitting thelowering of a traveling bucket to a sufficient distance to allow coaldischarged i'roin the hopper to fill the bucket. In t e constructionhitherto provided the bucket was lled directly from the hopper, the coalbeing allowed to iow from the hopper into the bucket by operating agatevalvev with which the hopper is equip ed. A serious disadvantagearisinl from t ese constructions is that the disc arge-end of the hopperand the bucket, when the latter was in position for filling at thebottom of the pit, werein darkness with the result that the operator inoperating the valve of the hlper would often-not allow the coal to runciently long to fill the bucket necessitat- V ing the rcloweringof thelatter withloss of time, or the elevating of a short load; or on theother band would be allowed to run too long causing the bucket to runover and depositing coal in the pit with the result of necessitating thedifficult work of removing the s )illed coal from the relatively deeppit. knot er great objection to constructions as hitherto provided isthat 4in the use 'of the manually-o v erated valve used 'they are a )tto become c ogged by the coal with the resu t of causing the pit to filland if the bucket is 'in the pit at the time, burying it.

My primary obfe'ct is to overcome the` objections to constructions oithis character as hitherto provided; and to roduce av constructionwhereby the coal will be discharged from the hopper iirst with a loaderandthen into the bucket or other receptacle.

Referring to the accompanying drawings: Figurel is a view in elevationof coaling apas indicated at 22, to ena Patented @rime s, '1909.

paratus constructed in accordance with my invention, the storage-bin andpit-wall being shown in sectional elevation, this view illustrating theloader- )roper in its normal position, in which it fills, and the bucketin one of the iositions it assumes intermediate the ends o its travel.Fig. 2' isv a View like that of Fig. 1 showing the position the parts assuine when the bucket reaches its lowermost position in the pit and theloader is operated to discharge its contents into. the bucket.

. Fig. 3 is a view in front elevation of the apparatus of the precedingvfigures, the view representing the parts in the positions shown inFig. 1. Fig. 4 is a view in sectional elevation of the loader and itsaron mechanism; and Fig. 5, a section ta en at the of the arrow.

The lower discharge-end pol'tioii of a hopl per for coal or the like, isrepresented at 6,

this hop er being preferably arranged belowy lthe leve of arailway-track (not shown) to permit the coal, or otherrnaterial, to bedumped into the hopper directly from cars on the track. The hopper is soconstructed as to afford as ace 7 immediately below the lower ends oftue conveying -l'oo'rsS and 9` with a cross-timber 1() extendingentirely' across this s ace. This space 7, opens into the pit in w ichthe bucket 1], hereinafter described, is operated. Located between the sace 7 and the pit are vertical uprights 12 a jacent and secured to awall 13 of the hopper `6. The bucket 11 for receiving coal line 5 onFig. 1, and viewed in the direction tates the provision of a pitadjacent to it, for

from the hopper and elevatimlr it to the sur face to dump it into a recetaclle for. receiving it, has rollers 13L on its si es which operate invertical guides 14 for guiding the'bucket in its movements, the bucketshown being of the ordinary form with an open top. The lower end-portionof the floor-section 9 is cut away to form an outlet linlwhich a chute-'section 16 havin curved outer edges 'as indicated, aty 17 is ocated. pl

Loading lmechanism for receivin a predetermined aniountof coal is locateintermediate the outlet 1.6 and bucket. The loader is in the form of asemi-cylindrical receptacle 18 having a iiat bottom 19, sides 20 andaninclosing wall 21. The receptacle is pivoted at its opposite sides atpoints equidistant between its ends to the o osed `uprights 12, Eb e thereceptacle to be rocked endwise. The wall 21 contains an Vopening 23from side to side 'tiepw sition of the receptacle as represented AinFig. l registers with the outletl iti from the hopper and` in theposition represented in Fig. is out of registration wit i it. 'l`he wallil also contains a discharge opening 24 and supported on the receptacleadjacent to this closes the receptacle has hlled und has been swung todischarge position, "the swinging olt the receptacle also operates toraise thc gate ISI. the slack in the fable H5 being sufficient io causethe gate to be raised to eoinplctelj. uncover the outlet 2li byilutiine-tlie receptacle has swung to diwliarge position, thiI ell'ectol' running` ih'l cable it". over the puliej.' ilo. as described, i'turing the gate. when it .starts to rise. to .suore twice as fastas thereceptacle lb. and lhi` the Inte need not be constructed so as lo star!to rise until the receptacle has snuiuz to nithin u slioit distance ofits lon'erinofa position. .\.s the receptacle swings. don'nn'ard at iisdi`H outlet lo -cliarge-end the links 23S are caused to lili downward attheir upper ends illus rausiugr at their inner ends on the rods 33 andunited at their outer ends by a curved plate 1'34 which is so locatedand is of such a size as to ada )t it to completely close the opening.24 in tlhe receptacle-when the loader is in the position hereinafterdescribed. The gate is connected to the lower end of arable 35 whichextends over a pulley 3o and connects l trated in iig.

at its opposite end to a hook 37 on the 2 loader-wall 21, a weight 37being secured to the cable between the hook 3f '1 and pulley-16.

'l heraising of the gate-valve 31 periniis the coal to freely dump from thereceptacle 1S into the bucket 11, which thus hlled. is raised in anysuitable manner. .1s thtl biuket 11 rises a roller '16 thereon engageswith the and . tilts the receptacle 1H. backward toward its rl`lienormal position yof the receptacle 1S is j that illustrate( in Fig. l inwhich it extends l hopper, its gate 31 closed, andthe apron 2:)withdrawn, by reason'et its connection at its t rod 26 with the links 3Sfastened to the opposite ends of a rod 39 journaled in brackets i 40 onthe uprights 12, levers 11 being secured to the inks 38 and carryingadjustable f weights 42, whereby the tendency of the weights is to tiltthe rods 3S upward and withdraw the apron.

bucket 11, this function beingaccomplished normal position, the openingbeing so located, as described, as to cause coal to begin to llow intothe receptacle. 1S as soon as it. has been moved a slight distance, thecoal thus falling upon the bottom of the receptacle to the left of the.center of gravity in r ig.

; 2, causing the receptacle to quickly complete its movement to 'normalposition in which it rents at its rear end on the cross-beam il). T heswinging of the receptacle to normal po sition causes the gate 31 toclose, the weight IS7 merely being heavy enough to cause the ln theuorinal position 'of the receptacle 18 as .described the coal with thebucket. 11. Y iacle to normal position also causes the liu automaticallyby two rods 43 pivoted near their upper ends to the sides of thereceptacle 1S and at their lower ends connected with a cross-bar 44which is caused to extend into the path of the bucket 11 by confinementbetween the meinbers of the bucket-guides 14. Thus as the bucket nearsthe limit of its descent it en gages with the bar 44, drawing down therods 43, and thereby tilting the receptacle to i the positionillustrated in Fig. 2. i the receptacle swings on its pivots, the coaldischarged into it while in normal position, llows toward its outer endand the reniainiiig unfilled. space in the. receptacle is Ylilled by thecontinued flow of coal 1n. to it so long' as the outlet 16 remains open.By the time the slack in the cable 35 to extend between ilul pulley 3band the hook 37a, and thus the cable 35 is prevented from becomingtangled The tilting of the recep- XS 3S to beA rocked to the positionindicated in Fig'. 1, thereby moving the apron 25 to a pt sition inwhich it does not extend into the path of the bucket 11. The provisionof the weight 42 serves to assist in turning the receptacle from its duming position to norinal, filling position an also aids in overcoming thegreat weight. on the outer end of the receptatle when turning te dumpingposition,

To avoid )ossible damage tothe loadermechanism should it extend in.discharging position when the bucket is moving donn-- ward, l slot thesides of the apron, as indicated at 47, and thus the apron will becaused to yield downwardly atI its outer end when so engaged by thebucket and the latter ina)- move to its lowermost position without doinganv daina'e. 1

, n lo avoid the leakage of coal, espeeialiythe lift) iineparticles orsmalllumps thereof from the and the outlet 16 falls 'upon the lip andpasses into the receptacle 18.

By thus provmmg the loader intermediate the hopper and bucket, it isimpossible 'to open the bin to cause it to discharge its con--z tentsinto lthe pit, as described of previous constructions; and it is alsoimpossible to overload or' underload a bucket.

inventionisthat of enabling the buckets to be rapidly filled, vas theoperator is not'called upon to use. hi-s discretion in filling thebuckets as in the manner described of prior construction, the operationof my improved mechanism being entirely automatic. 'Furthermore as theloader receives a predetermined amount of coal, its discharge 24 may bemade considerably larger than the outlet of hop ercould practically bein constructions as liitherto provided, and thus the bucket may beloaded very quickly.

By cci'istructing apparatus of the'character set forth in accor ancewith my invention, thi.,` material to be transferred resting normali)yinthe loader after filling, is caused to shift in the loader as soon asthe latter begins to tilt and roduces a movement of the material throngthe bin-outlet during the operation of moving the loader from normal t-ovdumping position, and thus the portion 21 of the receptacle, acting asan undercut gate, readily moves through the iowing material, therebyavoiding danger of obstruction to the movement of the Iioaderbylodgment-of the material betweenthc portion 21 and the bin-outlet.

W'liile 1 have illustrated and described my invention as applied to acoaling station, I do not intend to limit it to its use in thisconnection but desire to protect itin its a plication to .any system towhich it may lfie applicable involving ythe transferring of mai terialfrom a hopper, bin, or the like, to con-v veyer rece tacles.

While means for controlli-ng Vthe supply to the loader as a part of thelatter, namely its'wall 21, l'. do not wish to-be understood aslimiting,- my invention to `such means as so far as cerfl tain ofv itsfeatures are concerned, any other means for controlling the supply tothe loader may be employed. l
